Miniaturized infrared detectors

Integration on a chip: Tremendous effects on spectrometers of different kinds – and in various fields

31-Oct-2022 - Extreme miniaturization of infrared (IR) detectors is critical for their integration into next-generation consumer electronics, wearables and ultra-small satellites. Thus far, however, IR detectors have relied on bulky (and expensive) materials and technologies. A team of scientists lead by Empa ...

Watching complex molecules at work

17-Jan-2020 - A new method of infrared spectroscopy developed at BESSY II makes single-measurement observation and analysis of very fast as well as irreversible reaction mechanisms in molecules feasible for the first time. Previously, thousands of such reactions have had to be run and measured for this ...

Mini-spectrometer: Smaller than a coin

09-Oct-2019 - ETH researchers have developed a compact infrared spectrometer. It’s small enough to fit on a computer chip but can still open up interesting possibilities – in space and in everyday life. Nowadays, a mobile phone can do almost anything: take photos or video, send messages, determine its present ...

Processes at the Surface of Catalysts

Using Infrared Spectroscopy, Scientists Detect that Oxygen Defects Act as Active Centers

12-Apr-2012 - In chemical industry, heterogeneous catalysis is of crucial importance to the manufacture of basic or fine chemicals, in catalytic converters of exhaust gas, or for the chemical storage of solar energy. Scientists of Karlsruhe Institute of Technology (KIT) and Ruhr-Universität Bochum (RUB) have ...
